A CORPORATION OF NEVJ YORK COVER ASSEMBLING MACHINE Application filed March 12, 1930. Serial No. 435,333.

My invention relates to a cover assembling machine, and I declare the following to be a full, clear, concise and exact description thereof sufficient to enable anyone skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings in which like reference characters refer to like partsthroughout the specification.

The object of the invention is to provide a machine for pressing the body of a paper container onto the cover or cap portion thereof, whereby the containers will be ready for packing and shipping. The machineeifects this result by employing two rotary tables, one located on a plane somewhat above the other to allow for the height of the cover portion of the container. Acting in conjunction with said rotary tables is an intermittent star wheel and a horizontally reciprocating member cooperating therewith, whereby to center the cap member concentrically and below the body member, in which position pressure is brought to bear on the bottom portion of the body member. it being in inverted position, whereby the adjacent wall of the body portion is sunk into the cover portion. The wall of the cover portion slips over the adjacent wall of the body portion. To this end the machine is desi ned to hold the cover portion in concentric alignment with the body portion. Although the specification and drawings illustrate the body portion of the container being forced into the cover portion. the reverse can be affected namely forcing the cap onto the body portion.

Furthermore, the machine can be easily and quickly changed or altered to accommodate different sizes of containers.

The object and details of construction will be understood by referring to the drawings in which:

Fig. 1 is a perspective view of the device.

Referring more particularly to the draw ings, the machine embodies the master shaft 1 that is supported in a frame 2. Master shaft 1 has mounted on one end a pulley 3 connected with a source of power by a belt, not shown. The opposite end of shaft 1 has fixed to turn therewith a bevel pinion gear 5 that is in mesh with bevel gear 6 adapted to rotate freely on vertically disposed stationary shaft 10 having hearings in frame 2. Table 11 and star cam member 12 that is spaced from the top surface of table ll'is adapted to rotate with bevel gear 6. Pins '7 connect table 11 with the hub 13 of gear 6. The periphery of table 11 is reduced at 18. Hub 9 of star shaped cam 12 is fixed to turn with the hub portion of table 11 by tapered pins 14, 14. Cam member 12 is star shaped and bears against roller 15 mounted on an eccentric stud 16 carried in bear n s formed in horizontally reciprocating member 17. Mounting of roller 15 on eccentric stud 16 allows for a given amount of adiustment of the movement of member 17. It has an open recess for hous ng roller 15 and a so for th projection of the perimeter portion of star cam 12. Member 17 is screw mount d to the ends of shafts. 20. 20 which slide in h ar n s in stationary block 21. Stationary block 21 is held to the upper end of shaft 10 by a tapered pin 22. Shafts 20, 20 project through and beyond block 21 and are connected at their free ends by cross bar 23. Nuts 24. 24 are screw mounted to said free ends, whereby to hold cross bar 23 from slipping off therefrom. Coiled springs 25. 25 are mounted on shafts 20, 20 and in each instance hear at one end against cross bar 23 and at the other against an intermediate disk 26 that is free to slide on shaft 20. A coiled spring 27 of greater tension is disposed about each of whereby to facilitate a quicker retraction of 7 member 17. On the other hand cam 12 will force member 17 forward into the dotted line position illustrated in Figs. 1 and 2 from full line position illustrated in; Fig. 3 against thetension of said springs 25 and 27, on each of shafts 20. An adjustable counter weight 28 is supported on shaft 29 that is in turn mounted to cross bar 23, whereby to effect a balance to member 17.

The forward part of member-17 is concaved at 30. There is disposed within said concaved' portion a sector shaped member 31' which is held to member 17 by a screw bolt 32 that allows for a little play or movement of sector member 31. For which purpose also the arc of member 17 is on the circlev of a larger diameter than the arc'ofscctor member 31. This play or movement of sector 31 will permit the centering of said sectormember 31 with reference to cover portion 33 and body 34- of the container when member 17 is moved into dotted line position illustrated in Figs. 2 and 3, whereby to assist with the aid. of'star shaped member 35 in holding said cover portion 33 and body 34 thereabove in perfect alignment the one with the other. The lower portion of sector member 31 and of the recesses in star shaped member 35 are enlarged in diameter at 36 to accommodate the larger diameter of' cover 33 of the container.

Star shaped member 35 has five such'concaved recesses 37@ I't-is held to adjustable sleeve 38 by screw bolts 38a and ismonnted to rotate with shaft lO which is screw threadied at its lowerend to table 39 of frame 2. The means for adjusting sleeve 38, whereby to move star member35' up'or down to. accommodate covers having sidewalls of different height embodies a screw bolt 11 mounted to head part 42 that is bolted-M343 tof sleeve 38. The lower-end of'bolt ll is concaved'to conform to the round surface'ofanti-trio.

, tion ball e4 resting on the top of shaft 10;

Turning; of bolt 41 raise or lower star member 35 according to the direction in which bolt ll'turns. A second adjustable star shaped member 15 is mounted. on sleeve 38 and held above member 35 by set bolts46, whereby to anticipate containers. varying in height. 1

A grooved pulley 51'is formed integral withthe lower surface of star member-35" and is connected by a belt 52 with a grooved pulley53 fixed to turnwith hub 54: hereinafter men ioned. Y

Hub 54 is mounted on stationary shaft 55 which has a bearing' in frame 2. Beveleo gear 56- is formed integral? with the lower end of hub 54 and is in mesh with beveled pinion 57. Pinion 57 is fixed to'ro-tate with auxiliary shaft 58 that has bearings in frame 2. Shaft 58 is connected to master shaft 1 by sprockets 59, 60 and sprocket chain 61.

Table 62 is bolted to hub 54;, whereby to rotate with gear 56. A stationary table 63 is spaced above table 62 by its hub 6-1 which is 3 fixed tostationary shaft 55 by tapered pin 66.

Rails 70, forming. aguide-way or channel for the passage of body portion 34; of the con tai'ners are supported above the surface of table 62 by brackets 71, 71 mounted to stationary table 63. V Whereas guide members 72, 7 2 supported above table 11 aids in directing covers. 33 towards" their location between sector member 17 and the corresponding sector recess 37 of star shaped member 35. Bracket 7 5' mounted to member 10 supports one of the gui'de members 7 2and bracket'76 mounted to frame 2 supports the other.

The mechanism for pushing body portions 34' of containers'down into cover portions 33 embodies a disk fixed to the lower end of shaft 81 which has a sliding bearing in; horizontal bar 82 of frame 2. 'An adjustable collar 83 is secured to shaft 81 above bar 82. Lever 86 is bifurcated at one end and connected by links 87, 87 to collar 83'. It is fulcrumed at 90 to an upstanding bracket 91 mounted on bar 82' of'f'rame2, The opposite end of lever 86 is pivoted to a vertically reciprocating rod 92 that passes down through a guide sleeve 93v fastenedto frame 2. The lower end of'rod 92is bifurcated for mounting a roller 95 that isin contact with cam 96. Cam 96' is mounted'to'turn' with master shaft 1. A coiled spring '97 mounted on shaft 81 retracts disk 8 v I A chute directs the capped containers away from the machine and towards a packing box not shown. To this end-an endless chain 106 having'raised portions107 disposed at equal intervals-thereon, whereby to carry the assembled containers therebetween is. mounted onv sprocket wheel 110 fixed to turn. with master shaft 1' at one end and an idler, not shown, atthe other.

A plate111 supported by frame 2 is located at theedge'of table 62 whereby to bridge the space'between tables 62 and 11 for the passage of bodies 34: of the containers.

The means for intermittently rotating star shaped member 35; whereby it will remain stationary long enough for. disk 80. to press body 3 1 into cover33 embodies a brake member 115 adapted to arrest the rotation of star shaped j member 35 periodically. Brake member'115 has a horizontal arm 116 fastened thereto. Arm 11 6 is adapted to lie in the I path of one of the d'epending pins 117 that when the free end of member 115 is depressed. The rear edge of arm 116 is beveled at 118 to slide past pin 117 should it return before pin 117 has moved away. Brake member 115 is pivoted at one end as at 120 to frame 2. It carries on a stud 121 near its other end a roller 122 adapted to make contact with wheel 123 having depressions 12 1, 121 at diametrically opposite positions, whereby to allow arm 116 to descend by gravity out of the path of a depending pin 117, and, thereby release star member to continue its rotation. A coiled spring 119 attached at one end to member 115 and at the other to frame 2 will assure the depression of arm 116 at the proper interval. During the interrupted rotation of star member 35, pulley 51 will slip relative to belt 52.

The operation of the device is effected by placing body portions 3 1- of the containers on rotary table 62 between guide rails 70, whereas covers 33 progress by way of chute 126 and table 11. As bodies 34 are carried around on table 62 towards intermittent rotary star shaped member 35 they will be pushed into one of the concaved recesses 37 by the oncoming bodies 34. Star shaped member 35 aided by rails 70, 70 will thereupon carry said body portion around to a position opposite sector member 31 and directly above cover 33 which is advanced simultaneously by rotary table 11. As body portion 3 1 is moved directly over cover 33 in perfect aligned position, simultaneously brake member 115 will stop the rotation of star member 35 by arm 116 engaging the contiguous pin 117, and disk will descend under the influence of cam 96 on master shaft 1, to which it, disk 80, is indirectly connected. Immediately body 34 has been pushed into cover 33, disk 80 will rise under the pressure of spring 97, arm 116 of brake member 115 will be lowered by roller 122 dropping into one of the depressions 124 of wheel 123, whereby to allow star shaped member 35 to rotate and bring the next body portion 31 of the container into assembling position. Likewise, sector member 31 will be retracted by coiled springs 25, 27 on each of shafts 20, whereby to allow the next cover 33 to move into position under the rotation of table 11, whereas the assembled container will move out of assembling position under the same rotation of table 11 and into chute 105 where it is conveyed to destination by endless carrier chain 106. Chute 105 is supported by frame 2. Its side rail 130 which tends to direct the containers 34: into chute 105 is supported above table 11.

Having thus described by invention what I claim is new and desire to secure by Letters Patent is as follows:

1. In a cover assembling machine, a rotary member for carrying covers, another rotary member for carrying containers, a star shape member disposed adjacent to said rotary members, means for intermittently actuating said star shape member, whereby to dis pose said containers over said covers and means co-operating with said star shaped member for holding said cover and container in pre-determined position and another member for forcing said container into said cover.

2. In a cover assembling machine, a rotary table for carrying covers, a second rotary table located to one side of said first named rotary table for carrying containers, a star shape member disposed adjacent to said tables for disposing said covers and containers in alignment, means for interrupting the rotation of said star shape member, another member located on one of the said tables for oo-operating with said star shape member, means for moving said last named member forward to hold the parts of the container while the star shape member is stationary and a plunger member for pushing said containers into said covers.

Intestnnony whereof I have afiixed my signature.
